Re: Lucene Unicode Usage

So you got a utf8 encoded text file. But how do you read the file into  
Java? The default encoding of Java is likely to be something other than  
utf8. Make sure you specify the encoding like:

  InputStreamReader( new FileInputStream(filename), "UTF-8");

I'm building an index from a FileMaker database by dumping the data to a  
tab-separated file.  Because the FileMaker output is encoded in  
MacRoman, and uses Mac line separators, I run a script across the tab  
file to clean it up:
	tr '\r\v' '\n ' | iconv -f MAC -t UTF-8
This basically converts the Mac \r's to \n's, replaces FileMaker's vtabs  
(for inter-field CRs) with blanks, and runs a character converter to  
build utf-8 data for Java to use.  Looks fine in jEdit and BBEdit, both  
of which understand UTF.

BUT -- when I look at the indexes created in Lucene using Luke, I get  
unprintable letters!  Writing programs to dump the terms (using Writer  
subclasses which handle unicode correctly) shows that indeed the files  
now have odd characters when viewed w/ jEdit and BBEdit.

The analyzer used to build the index looks like:
     public class RedfishAnalyser extends Analyzer {
       String[] stopwords;
       public RedfishAnalyser(String[] stopwords) {
         this.stopwords = stopwords;
       }
       public RedfishAnalyser() {
         this.stopwords = StopAnalyzer.ENGLISH_STOP_WORDS;
       }
       public TokenStream tokenStream(String fieldName, Reader reader) {
         return new PorterStemFilter(
             new StopFilter(
                 new LowerCaseFilter(
                     new StandardFilter(
                         new StandardTokenizer(reader))),
                stopwords));
       }
     }
Yikes, what am I doing wrong?!  Is the analyzer at fault?  Its about the  
only place where I can see a problem happening.

Thanks for any pointers,
Owen
